Answer:
807.21 fl oz
Explanation:
To add 15 liters (L) to 300 fluid ounces (fl oz), you'll need to convert one of the units to the other to ensure they are in the same unit of volume before adding them together.
1 liter is approximately equal to 33.814 fluid ounces (fl oz).
So, to convert 15 liters to fluid ounces:
15 L * 33.814 fl oz/L = 507.21 fl oz
Now, you can add 507.21 fl oz to 300 fl oz:
507.21 fl oz + 300 fl oz = 807.21 fl oz
So, 15 liters plus 300 fluid ounces is equal to approximately 807.21 fluid ounces.
